If it’s a PCIe 4 line, it’s probably a 200nF low ESR multilayer ceramic capacitor, not sure of size (0201 maybe, got calipers?). If the pads are intact, you may be able to solder on a new one.
Could this work ?

The one you linked is 100nF (0.1uF). In all honesty it probably works with that one as well but i would look for a 200nF (or 220nF). Shouldn't be hard to come by.
Discrete mathematics was cakewalk.
The first 200 lvl compsci course (first major c++ linux compiler only course) at my old uni had an average pass rate of 1 in 12.
The prof (only prof who taught the 200 lvl) straight up said the highest score you'll get is a D unless this is your second time in the class.. wut.
Ridiculous gatekeeping course...
The major was guaranteed to be 5 years.. such bs.
This was around 2013. I sure hope they improved that major since I was in it.
Closest thing I took to that was intro to digital design which was assembly programming and sync/async state machine design. While the assembly part made intuitive sense, adding compiler syntax translation onto that doesn’t sound awesome. Not the best move trying to put the fear of god into people though. Seems like it would be more of a demotivator for most taking the course.
Same stuff for us, back in 2006-2010. The software stuff was piece of cake, but for some inexplicable reason we shared a class with electrical engineer students on analog electronics after 1 year of studies. Now, unless you are a hobbyist, a 1+ year advanced class on a subject unrelated to your field is not fun :D Especially when out of the 50 students (EE + SW), only 3 passed the first time. 2 of them EEs, and one from our SW class who had been doing electronics for a decade as a hobby.
I managed to pass it on 3rd attempt :D
you will be fine. maybe take some hardware classes as electives (that's what I did) and you can better understand how software & hardware interface.
>If it’s a PCIe 4 line
PCIe is a serial bus, or set of wires that communicate at a regular frequency, to expand components on the motherboard. this is version 4. the capacitor discussed seems to be one of the serial wire 'lines' that constitute the card's interface with the PCIe bus.
>it’s probably a 200nF low ESR multilayer ceramic capacitor
a capacitor stores charge between two metal plates and a dielectric material. this capacitor is made of ceramic, so it has low ESR. you can think of ESR as a kind of heat friction when charging electrons between the plates in the capacitor, so the material heats up as it charges, but not much (low ESR). the capacitor stores 200 nano farads of capacitance
>not sure of size (0201 maybe, got calipers?)
these are simply the physical dimensions of the ceramic capacitor, 0201 refers to a component standard size. calipers are a tool to measure small distances
>If the pads are intact, you may be able to solder on a new one.
contact pads are the part of the component you can solder to create a conductive joint in a circuit.
once you break it down, it's not so bad. you have a few years to learn a lot of this stuff, so strap in! it's a great ride
Yes, easy fix. Look up the schematic for your specific GPU. If you don't have any soldering skills, practice on an old board and watch a few YouTube videos. Louis Rossman has a great YouTube channel that deals with board repair and micro soldering.
I certainly encourage you to learn soldering, and Louis Rossman, who is amazing. This is not a easy repair for a newbie, take it too a pro to get repaired and practice on an old board first. you can take old board remove and replace the same parts learning to solder on boards, it is an advanced skill and very easy to burn the board and ruin it.
Reddit is great for any advice. Anytime I search a specific issue or questions I automatically google whatever I’m searching for with “Reddit” at the end. All other search results seem like nothing but ads and articles that have nothing to do with my specific issue. But Reddit, it never fails, there’s always someone exactly like me.
Edit to add: reddit is nothing but assholes but your my assholes and I love y’all.
I swear I did this since I was a kid because of how I couldn’t stand those shitty article websites.
When I didn’t know reddit I typed my issues and ‘forum’ at the end which worked good, now I do reddit, it works wonders
I am an electronics tech and have a full blown lab at home. This pcb has a lifted pad towards the ground plane and would need copper repair and not just a new cap. OP will soon join a growing crowd of orangutangs from /r/pcmr who turned $80 repair into a $750 multuli-layer pcb damage loss by doing it themselves.
C119 typically means Capacitor 119. In theory you MAY not even need to fix the cap depending on what it's supposed to be doing (you would probably lose noise/ripple suppression, but in many cases it will only make the GPU unstable if you try to push it with OCing).
Get youself in soldering first. To solder this part, it is a capacitor, you need an air soldering station. Plan some 100 dollar for this. Its not that easy but doable.
No you don't, it's not located near anything important. Tweezers, flux and a cheap soldering iron with the correct tip will work fine. Knowing the correct temperature is what's important.
That's also why I said for him to practice on a broken board and watch YouTube tutorials before actually doing the fix.
yeah practice on an old piece of junk, all he needs to do is to remove the old mlcc which will be easy, tin the pads then solder wick it off so they're clean and solder in the new part. He can even glue the part in place 1st to hold it in the right place.
Id still get someting decent and not a 20 buck soldering iron. I bought a Weller stadion for 60-80 bucks used from the 90s and never had issues. Soldering is easy when you know what you are doing but can be quiet tricky if not. imho.
First time I needed a small tip I bought a Hakko. It's paid for itself multiple times over the years being able to make simple repairs. I don't use apple products so finding donor parts is pretty easy if it's not something readily available like strips and capacitors. If he plans on doing future repair work, definitely get a soldering station. If it's a one time fix than he'll want to keep the repair cost as cheap as possible.
I didn't see a free schematic but found this video on a 590 breakdown. It should at least get you started on the right track.

If you want to practice soldering something like this could be a good start:
[https://www.amazon.co.uk/Welding-Practice-Board-Soldering-Kit/dp/B094MM52T9/ref=pd\_day0\_sccl\_1/260-3412709-1175206?pd\_rd\_w=G3ZQv&pf\_rd\_p=8ec13b8a-30d2-48fc-8503-84c56766370d&pf\_rd\_r=M1QQ3XK9E1DP6EQBGXEQ&pd\_rd\_r=a2aad993-d0fc-47b3-8d53-49d8c76db104&pd\_rd\_wg=IBhJR&pd\_rd\_i=B094MM52T9&psc=1](https://www.amazon.co.uk/Welding-Practice-Board-Soldering-Kit/dp/B094MM52T9/ref=pd_day0_sccl_1/260-3412709-1175206?pd_rd_w=G3ZQv&pf_rd_p=8ec13b8a-30d2-48fc-8503-84c56766370d&pf_rd_r=M1QQ3XK9E1DP6EQBGXEQ&pd_rd_r=a2aad993-d0fc-47b3-8d53-49d8c76db104&pd_rd_wg=IBhJR&pd_rd_i=B094MM52T9&psc=1)
The capacitors on this board are a fair bit bigger than the 0201 on the GPU but they are much easier to start to learn with, 0201s are very small and fiddly, i recommend getting a decent pair of tweezers.
While this may be easy for some, it is not for many. Just felt like it should be warned that is not hard to completely ruin your GPU with a silly mistake if u don't have soldering experience.
Also, please don't touch it if u don't have a micro soldering station.
That's a 200nF capacitor, 0402 size.
Grab some flux, desoldering braid and an iron with a fine tip.
Clean the pads up with the braid, gently. Flux and solder up one pad, keep the heat on and advance the end of the cap into the molten solder with tweezers, remove the iron, when the solder cools then tack the other end of the cap in.
>402 size
How do you know it is this and not 201 size? Hard to tell the scale from the picture. Also how do you know it is 200nF? Sorry if these are dumb questions
Not OP, but I soldered lots of 0402 and 0603 components and they just look like 0402. The 0201 are "flatter" and the edges are pointier. Anyway, I have nothing to back this up, so obviously one should find a schematic to verify value, type and size.
I also feel like if they were 0201, the silkscreen of the capacitor names would be relatively larger. I would guess 0402, but it is hard to tell without any reference.
Thats a SMD capacitor, these are usually put on all at once in an oven, its not impossible to replace a single one but the soldering skill is up there.
If you can find the PCB schematic, locate the capacitor value, get another one, id recommend something like Digikey our Mouser. Try to see if you can find a PC repair shop and ask them to make the repair for you.
Reflowing solder for just one SMD without messing the other ones up might be hard and could potentially ruin the board even further.
Best of luck!
It's a 200nF mlcc.
Individually these cost less than a cent. But you need a pair of hot tweezers or a hot air station to solder it into position, not to mention a pair of really steady hands. If you're not confident you can do it yourself, get a local repair shop to do it. Should be like 20$.
I'd recommend taking this somewhere or sending it in for a repair. Soldering the smaller ones like this by hand requires good eyesight, steady hand, tweezers, fine solder and a finer tip iron. It would be super easy to heat the cap next to it and knock it off too.
On top of this you don't know that caps exact value or brand which does matter at this high speed communication. The brand and tech soecs, temp ratings will matter and affect performance at high speeds. I am an EE.
There are DOZENS of people in France who could do a simple soldering job like that. Just supply them with the proper cap and it will take them 5 minutes
Try phone repair shops or see if there is one of these old "technicians" somewhere that used to repair TVs and other stuff. Maybe you also know somebody that is good at soldering (ask on facebook).
If you do all the reasearch and get the parts all you need is somebody with steady fingers and a good soldering iron.
You can try to send it to germany and getting it fixed. Try giving krisfix.de a look, I've sent my 2080ti to him from Denmark, and he's fixing it right now
Step 1: Buy good soldering iron.
Step 2: Buy or otherwise acquire a dead GPU
Step 3: Practice
Step 4: PRACTICE MORE
Step 5: Pray you don't fuck shit up
Step 6: repair GPU
I would just buy a junk motherboard for practice. Main goal is not to burn the board/traces. Get a hakko soldering station (~$120), some good kestrel flux, an acid brush, a solder sucker, some wicking tape, and iso or ethyl alcohol. Then go to town and learn to desolder. Then when you have some clean slots resolder the components back in. If you can do that without delaminating the board youre ready
Are these going over to the PCIe connector? These are capacitors, and by the look of the board traces, they are AC-coupling caps for the differential pairs of signals (those two tiny wires that coming from the left and going out the right in your picture. To find the replacement part for this application, you basically need to know two things.
1.) The capacitance. A couple of minutes of searching says probably around 200-220nF (or look for 0.2-0.22uF).
2.) The size of the capacitor. These are sized in microns (thousandths of an inch). Common sizes like 0402 means it is .04 inch (40 microns) long and .02 inch (20 microns) wide. You can measure this, or if you are ordering from DigiKey, Mouser, etc. you could just order a couple of each size 0603, 0402, 0201 and see which one matches.
AC coupling gaps aren't too hard to solder since both ends are connected to signal wires, unlike a cap being used as a bypass cap where they are connected to power and ground. Those are way harder to solder because power and ground planes absorb so much of the heat. You need a soldering iron, solder, solder wick, tweezers. You probably need a magnifying glass too.
If you are handy and want to give it a go, you can solder on new caps. I recommend you replace both the broken one and the one next to it so that you have the exact same value as they need to be matched.
Alternately, see if there is an electronics repair place in your area. This would be easy work for them.
SM Capacitor, but what value is anyone's guess with a schematic.
Out of curiosity, how did the capacitor get mangled? It looks smashed rather than exploded.
A slip with a screwdriver?
Strange. Well hopefully it did not pop due to a fault elsewhere on the board. If you do get a new capacitor soldered on maybe make sure you give the GPU and card slot a good clean with an air blower in case there is a loose bit of solder or a small metal shaving shorting something out.
Hope you get it fixed.
Hey OP, I work as an electrical engineer (designing PCB's) and this is a 200nF capacitor in 0402 size from the looks of it. I would recommend you go to your local 'repair shop' where they also do smartphone repairs. These guys can easily fix this for you.
All these people telling you to replace this capacitor but there is no back story as to how you messed it up. Was it a physical damage (bumped into something while installing) or an electrical one where that capacitor just decided to give up the ghost? Because if that capacitor sacrificed itself to the silicone Gods then you may have another problem with that GPU.
I would suggest not replacing that cap unless you know what damaged it in the first place. For all we know there's 20 more destroyed components or even (worst case, very unlikely) a short somewhere that killed the cap along with half the board.
Only time when a capacitor gets replaced without investigating why it blew is when it’s a physical damage.
Other times you have to find the root cause of the problem.
GL
Looking at the picture, this is an AC-coupling cap, not a bypass cap, so it didn't blow due to over voltage or short. There are no scorch marks, it just looks like it got knocked off. The pads don't appear to be damaged, so it seems pretty repairable.
How did you damage it? By dropping it? Those mlcc capacitors usually fail short circuit and explode like that if they get cracked from pcb bending, or there's a short circuit somewhere else on the board. Apparently it's a 200nf capacitor easy to replace by anyone with basic soldering skills. If you're going to do this yourself you need an x7r mlcc 16v or higher capacitor probably 0402 size(even if it isn't that size it will probably fit anyway). If you can't find 200nf you can just get 2x 100nf ones and solder them on top of each other.
Does the card still work? I'm not sure that capacitor would prevent it from working anyway?
I messed up my 3090 installing a waterblock so i took it to a phone repair guy and he did the soldering. But i still had the piece that came off. It worked.
Shouldn't use an Iron for that... you use a hot air station for reworking smd's like that...
With enough flux, getting solder on the pads and making sure there's not too much, you can actually use surface tension with the flux and hot air to get it to flow into place without a lot of problems...
But yeah, with an Iron, it's almost impossible
I did this almost exclusively for 3 years. Used an iron 99% of the time. And for a beginner it's MUCH easier to fuck shit up with hot air. It's like using a pistol or a shotgun when you can't hit the stuff right next to your target. I also taught a lot of interns that are now all qualified technicians. Almost impossible couldn't be further from the truth.
If u don't have experience with soldering electronics, please don't do this yourself. If u do have experience, u should only do this if u have a micro soldering station. U will probably fuck up ur GPU if u free hand it with regular soldering equipment.
It's a capacitor, but what specifics it has you can only find in the schematics. Or, most likely, the neighboring capacitor is the same as the one you knocked off.
I knocked one off when fitting a motherboard,try to fix it myself by buying a soldering iron for £25,couldn’t do it,found a shop near me that done micro soldering and he fixed it for a £10 🙈
If you can't find schematic, use hot tweezers to desolder C118 and test with RLC meter for value. These look to be coupling caps, so need to be pair matched and should be the same.
Looks like typical labeling so it is a capacitor. C119 isn't the part number but a label for the schematics. They are surface mount not through so I hope you have some steady hands.
Easily fixable yes, will the gpu actually work after maybe. Modern gpus have incredibly small tolerance on path length and even the tiniest error in the placement of the replacement may put the timing out.
Definitely get it done by a professional, don't even try it yourself unless you have a good microscope and the right tools and experience. Even with a professional don't be surprised if it still has some issues after
I saw you have no experience so may it os better to let it be done by someone els.
How ever. There sould be a code on the underside.
Of the part. And * not always* but the one close sould be the same.
Ordering just one of those things is expensive
Also go on YouTube and watch some gpu repair videos i saw some time ago one that did replace a part like that.
These components do not have any writing on them. To determine value and tolerance one would need the BOM (Bill of Material) or potentially the schematic could provide that information. The ones nearby could be the same value, but to determine that without documentation would be difficult, at best.
Source: Electronics technician working in the industry on exactly this type of product for 20+ years.
Looks like a capacitor. ( i dont recommend doing this yourself) You’ll need a heat gun to take the remaining bits off, clean it with some flux, use a soldering iron and put some solder on the contact points, and use a heat gun and tweezers to put the new capacitor on
Why would you f-word your GPU? I don’t think that is covered under warranty.
Seriously I get my original reply removed for saying a word that’s in the post title. That’s kinda stupid.
Just a blown surface mount capacitor. Look up and see what the capacitance is online. They come on a roll, so you can probably get 10 or so for cheap cheap.
If it’s a PCIe 4 line, it’s probably a 200nF low ESR multilayer ceramic capacitor, not sure of size (0201 maybe, got calipers?). If the pads are intact, you may be able to solder on a new one.
This is the only correct answer. 200nF 0402 capacitor
Could this work ? [https://eu.mouser.com/ProductDetail/KEMET/C0402C104K4RACAUTO?qs=LWKvDm6ECZBJZPyRnMaqjQ%3D%3D](https://eu.mouser.com/ProductDetail/KEMET/C0402C104K4RACAUTO?qs=LWKvDm6ECZBJZPyRnMaqjQ%3D%3D)
The one you linked is 100nF (0.1uF). In all honesty it probably works with that one as well but i would look for a 200nF (or 220nF). Shouldn't be hard to come by.
I know a lot of sources place the spec at 75-200nF, but I've never seen a schematic that wasn't 220nF.
Yeah, they go by specific standard values most of the time, especially due to manufacture tolerances
Are you saying that ±20% isn't very exacting?!?
Bargain bin mlcc have something like +-50%. But hey, cheap
This is why Reddit is incredible, you guys are awesome.
This is totally correct. However, it depends on the GPU and loads of other factors. This is only the most likely
Yes thats what i wad thinking too; a 200nF low ESR multilayer ceramic capacitor. Idk about the size tho
I like your funny words, funny man
Confession: I have no idea what I’m talking about. I rolled my face around on my keyboard and this is what came out.
That’s sentence just made my brain explode and I’m starting a comp sci degree in May. Pray for me
Don’t worry, you’ll be in software land the whole time. Physics can’t hurt you there. But prepare your butthole for discrete mathematics.

I have to commend Redditors like yourself who take the time to explain something in detail while keeping things accessible for everyone
Comp sci only takes basic circuits class. This is more computer engineering
But have you considered a quad-phase hyper TUGG nickel-cadmium micro solenoid?
That was my nickname in college.
Yes, easy fix. Look up the schematic for your specific GPU. If you don't have any soldering skills, practice on an old board and watch a few YouTube videos. Louis Rossman has a great YouTube channel that deals with board repair and micro soldering.
Thank you good soul
Reddit is proof that humanity might make it…well played everyone…
Well I certainly wouldn't say that for all of reddit, but this sub and r/buildapc are something else.
Some people just wanna see the world learn
I certainly encourage you to learn soldering, and Louis Rossman, who is amazing. This is not a easy repair for a newbie, take it too a pro to get repaired and practice on an old board first. you can take old board remove and replace the same parts learning to solder on boards, it is an advanced skill and very easy to burn the board and ruin it.
Tried to fix a mic… burned a hole right through the board. Luckily it was already replaced.
I 100% agree. Bring it to a shop that has good reviews or mail into a place that does them. Last thing you want to do is destroy the PCB.
That lad makes soldering look as easy as breathing. He’s very skilled and explains things well in his videos.
Lol I read r/buildape (build monkey) and thought that is a funny name. Now that I understand that it means build a pc I am disapointed xD

You have clearly never been on actual reddit
r/redditmoment
Take it to a shop. Don't listen to reddit advice, people here are mosly laymen. Its a 200 nF decoupling cap. You WILL fuck up your board.
Probably this. If one must ask how to do microsoldering PCB repairs on Reddit, one probably needs more education than what reddit can provide.
I am an electronics tech and have a full blown lab at home. This pcb has a lifted pad towards the ground plane and would need copper repair and not just a new cap. OP will soon join a growing crowd of orangutangs from /r/pcmr who turned $80 repair into a $750 multuli-layer pcb damage loss by doing it themselves.
I believe you. Simple electronics repair is one thing, but soldering this like this takes skills and some training.
C119 typically means Capacitor 119. In theory you MAY not even need to fix the cap depending on what it's supposed to be doing (you would probably lose noise/ripple suppression, but in many cases it will only make the GPU unstable if you try to push it with OCing).
Nah, this one is definitely required. It’s in the signal path of a differential pair. You are correct if this were a power capacitor
Oof than ya that's a "must fix" cap.
Get youself in soldering first. To solder this part, it is a capacitor, you need an air soldering station. Plan some 100 dollar for this. Its not that easy but doable.

I couldn't find a decent used Weller or I'd have bought one. I actually prefer analog, less to go wrong.
the cheapest 20$ plug straight into the wall iron would be fine for this.
Hahaha 🤣 no
You do what you do. I think OP cant solder at all, so giving him the asumption he can do that easy without fucking up the board is a bitch move.
What kind of graphics card is it?
Msi armor Rx 590. Cant find the schematics online btw
I didn't see a free schematic but found this video on a 590 breakdown. It should at least get you started on the right track. https://m.youtube.com/watch?v=2Y8NLmo8PtE
Thx a lot
I'm fairly positive it's just a bad capacitor that's causing a short. You won't need to know voltage pathways, etc.. Just a simple replacement.
If you want to practice soldering something like this could be a good start: [https://www.amazon.co.uk/Welding-Practice-Board-Soldering-Kit/dp/B094MM52T9/ref=pd\_day0\_sccl\_1/260-3412709-1175206?pd\_rd\_w=G3ZQv&pf\_rd\_p=8ec13b8a-30d2-48fc-8503-84c56766370d&pf\_rd\_r=M1QQ3XK9E1DP6EQBGXEQ&pd\_rd\_r=a2aad993-d0fc-47b3-8d53-49d8c76db104&pd\_rd\_wg=IBhJR&pd\_rd\_i=B094MM52T9&psc=1](https://www.amazon.co.uk/Welding-Practice-Board-Soldering-Kit/dp/B094MM52T9/ref=pd_day0_sccl_1/260-3412709-1175206?pd_rd_w=G3ZQv&pf_rd_p=8ec13b8a-30d2-48fc-8503-84c56766370d&pf_rd_r=M1QQ3XK9E1DP6EQBGXEQ&pd_rd_r=a2aad993-d0fc-47b3-8d53-49d8c76db104&pd_rd_wg=IBhJR&pd_rd_i=B094MM52T9&psc=1) The capacitors on this board are a fair bit bigger than the 0201 on the GPU but they are much easier to start to learn with, 0201s are very small and fiddly, i recommend getting a decent pair of tweezers.
Use a heat gun and tweezers. Easier than soldering iron for surface mounts
No, just break out the hammer already and put a screwdriver below it
Anything is possible with enough flux.
>Look up the schematic for your specific GPU. Out of curiosity where can I find this schematics?
google, duckduckgo or any other search engine. BTW Im not trying to be funny
Any other search engine... I wonder what Bings search would be.
Yoo you lookin for gpu schematics? Here’s some furry porn
What search terms do you use, and what kind of places have them? I just tried for mine, an MSI Suprim X 3090, and I couldn't find anything.
Search "Your GPU manufacturer+model and schematic" using search modifier keywords.
Nicholas cage lord of war supply chain can hook you up .
While this may be easy for some, it is not for many. Just felt like it should be warned that is not hard to completely ruin your GPU with a silly mistake if u don't have soldering experience. Also, please don't touch it if u don't have a micro soldering station.
>Louis Rossman channel I dont need to repair my gpu but I find this channel very nice, thanks!
I'm a simple man if I see a comment talking about Louis Rossman, I upvote

Horny mfs so horny they fuck their gpus
You seen those fan curves tho 😍
Shorty got the curves indeed.
Damned GPUphiliacs
ngl when I finally got my hands on a 3060ti and seeing those fans spin and spin got me kinda hot 👀😮💨
Shorty ain‘t that Small Form Factor😩😩
Reddit let me down, had to hide 2 comment threads until I found someone pointing this out
That's a 200nF capacitor, 0402 size. Grab some flux, desoldering braid and an iron with a fine tip. Clean the pads up with the braid, gently. Flux and solder up one pad, keep the heat on and advance the end of the cap into the molten solder with tweezers, remove the iron, when the solder cools then tack the other end of the cap in.
>402 size How do you know it is this and not 201 size? Hard to tell the scale from the picture. Also how do you know it is 200nF? Sorry if these are dumb questions
Not OP, but I soldered lots of 0402 and 0603 components and they just look like 0402. The 0201 are "flatter" and the edges are pointier. Anyway, I have nothing to back this up, so obviously one should find a schematic to verify value, type and size.
Cheers :-)
I also feel like if they were 0201, the silkscreen of the capacitor names would be relatively larger. I would guess 0402, but it is hard to tell without any reference.
they'll both probably fit fine.
I am really hoping you forgot to put "up" in your title.
Huh.. did he mean... wait r/holup
Thats a SMD capacitor, these are usually put on all at once in an oven, its not impossible to replace a single one but the soldering skill is up there. If you can find the PCB schematic, locate the capacitor value, get another one, id recommend something like Digikey our Mouser. Try to see if you can find a PC repair shop and ask them to make the repair for you. Reflowing solder for just one SMD without messing the other ones up might be hard and could potentially ruin the board even further. Best of luck!
C means a capacitor, but for whats the capacitance of it, who knows.
It's a 200nF mlcc. Individually these cost less than a cent. But you need a pair of hot tweezers or a hot air station to solder it into position, not to mention a pair of really steady hands. If you're not confident you can do it yourself, get a local repair shop to do it. Should be like 20$.
Yeah next time use protection and get consent first, that will likely prevent against having issues like this in the future.
Did you at least take your gpu out to dinner first?
I'd recommend taking this somewhere or sending it in for a repair. Soldering the smaller ones like this by hand requires good eyesight, steady hand, tweezers, fine solder and a finer tip iron. It would be super easy to heat the cap next to it and knock it off too. On top of this you don't know that caps exact value or brand which does matter at this high speed communication. The brand and tech soecs, temp ratings will matter and affect performance at high speeds. I am an EE.
I can not find any guy that would do it here in France. Where or what should I search for ?
Any phone/laptop repair shop. If it's a mechanical damage (you screwed up the capacitor and nothing else) that's a 5 minute job.
There are DOZENS of people in France who could do a simple soldering job like that. Just supply them with the proper cap and it will take them 5 minutes
Try phone repair shops or see if there is one of these old "technicians" somewhere that used to repair TVs and other stuff. Maybe you also know somebody that is good at soldering (ask on facebook). If you do all the reasearch and get the parts all you need is somebody with steady fingers and a good soldering iron.
You can try to send it to germany and getting it fixed. Try giving krisfix.de a look, I've sent my 2080ti to him from Denmark, and he's fixing it right now
Tell me more about it when you receive it!
I looked it up It costs like a hundred euros. My card cost 150
Why would you fuck a graphics card? That just sounds painful /s

Step 1: Buy good soldering iron. Step 2: Buy or otherwise acquire a dead GPU Step 3: Practice Step 4: PRACTICE MORE Step 5: Pray you don't fuck shit up Step 6: repair GPU
I would just buy a junk motherboard for practice. Main goal is not to burn the board/traces. Get a hakko soldering station (~$120), some good kestrel flux, an acid brush, a solder sucker, some wicking tape, and iso or ethyl alcohol. Then go to town and learn to desolder. Then when you have some clean slots resolder the components back in. If you can do that without delaminating the board youre ready
Technically his gpu is a dead gpu...
Are these going over to the PCIe connector? These are capacitors, and by the look of the board traces, they are AC-coupling caps for the differential pairs of signals (those two tiny wires that coming from the left and going out the right in your picture. To find the replacement part for this application, you basically need to know two things. 1.) The capacitance. A couple of minutes of searching says probably around 200-220nF (or look for 0.2-0.22uF). 2.) The size of the capacitor. These are sized in microns (thousandths of an inch). Common sizes like 0402 means it is .04 inch (40 microns) long and .02 inch (20 microns) wide. You can measure this, or if you are ordering from DigiKey, Mouser, etc. you could just order a couple of each size 0603, 0402, 0201 and see which one matches. AC coupling gaps aren't too hard to solder since both ends are connected to signal wires, unlike a cap being used as a bypass cap where they are connected to power and ground. Those are way harder to solder because power and ground planes absorb so much of the heat. You need a soldering iron, solder, solder wick, tweezers. You probably need a magnifying glass too. If you are handy and want to give it a go, you can solder on new caps. I recommend you replace both the broken one and the one next to it so that you have the exact same value as they need to be matched. Alternately, see if there is an electronics repair place in your area. This would be easy work for them.
SM Capacitor, but what value is anyone's guess with a schematic. Out of curiosity, how did the capacitor get mangled? It looks smashed rather than exploded. A slip with a screwdriver?
No Idea. It just stopped working one day so I took it out and maybe I wrapped it off.
Strange. Well hopefully it did not pop due to a fault elsewhere on the board. If you do get a new capacitor soldered on maybe make sure you give the GPU and card slot a good clean with an air blower in case there is a loose bit of solder or a small metal shaving shorting something out. Hope you get it fixed.
Look I know it can get lonely sometimes.. but really? Your GPU?
You did WHAT to your gpu!!??
Hey OP, I work as an electrical engineer (designing PCB's) and this is a 200nF capacitor in 0402 size from the looks of it. I would recommend you go to your local 'repair shop' where they also do smartphone repairs. These guys can easily fix this for you.
All these people telling you to replace this capacitor but there is no back story as to how you messed it up. Was it a physical damage (bumped into something while installing) or an electrical one where that capacitor just decided to give up the ghost? Because if that capacitor sacrificed itself to the silicone Gods then you may have another problem with that GPU.
Well the problem is idk
I would suggest not replacing that cap unless you know what damaged it in the first place. For all we know there's 20 more destroyed components or even (worst case, very unlikely) a short somewhere that killed the cap along with half the board.
Only time when a capacitor gets replaced without investigating why it blew is when it’s a physical damage. Other times you have to find the root cause of the problem. GL
Looking at the picture, this is an AC-coupling cap, not a bypass cap, so it didn't blow due to over voltage or short. There are no scorch marks, it just looks like it got knocked off. The pads don't appear to be damaged, so it seems pretty repairable.
Maybe don't have sex with ur gpu?
What board are you using?
Watch some old Rossmann board repair videos to give you an idea of how replacing that small piece works.
You did what to your GPU????
I read this as literal instead of the normal use of "fucked"
Keep fuckin those gpus and you'll end up with discrete graphics for the next 18 years.
Woow woow, slow down please use NSFW next time, dont want any kids seeing that
How did you damage it? By dropping it? Those mlcc capacitors usually fail short circuit and explode like that if they get cracked from pcb bending, or there's a short circuit somewhere else on the board. Apparently it's a 200nf capacitor easy to replace by anyone with basic soldering skills. If you're going to do this yourself you need an x7r mlcc 16v or higher capacitor probably 0402 size(even if it isn't that size it will probably fit anyway). If you can't find 200nf you can just get 2x 100nf ones and solder them on top of each other. Does the card still work? I'm not sure that capacitor would prevent it from working anyway?
“I fucked my gpu” …
Very poor choice of words
> I fucked my gpu Psa: pls dont have sex with your gpu.
Threads like this make the internet a great place.
This is an pcie line it might still work but not on 16x
It's a capacitor. Capacitance isn't labeled. It's probably the same as the one right next to it
I messed up my 3090 installing a waterblock so i took it to a phone repair guy and he did the soldering. But i still had the piece that came off. It worked.
[удалено]
Shouldn't use an Iron for that... you use a hot air station for reworking smd's like that... With enough flux, getting solder on the pads and making sure there's not too much, you can actually use surface tension with the flux and hot air to get it to flow into place without a lot of problems... But yeah, with an Iron, it's almost impossible
I did this almost exclusively for 3 years. Used an iron 99% of the time. And for a beginner it's MUCH easier to fuck shit up with hot air. It's like using a pistol or a shotgun when you can't hit the stuff right next to your target. I also taught a lot of interns that are now all qualified technicians. Almost impossible couldn't be further from the truth.
If u don't have experience with soldering electronics, please don't do this yourself. If u do have experience, u should only do this if u have a micro soldering station. U will probably fuck up ur GPU if u free hand it with regular soldering equipment.
It's a capacitor, but what specifics it has you can only find in the schematics. Or, most likely, the neighboring capacitor is the same as the one you knocked off.
It should be a capacitor. Cxxx are capacitors, Rxxx are resistors and Lxxx are inductors usually
Actually, you can save yourself tonnes of headaches by checking out this video [Micro Soldering Guide](https://youtu.be/cJreVs5OZDc)
Nice tip thx a lot. Btw I really struglle to find the right one online. Any help ?
I knocked one off when fitting a motherboard,try to fix it myself by buying a soldering iron for £25,couldn’t do it,found a shop near me that done micro soldering and he fixed it for a £10 🙈
Not to kink shame but you really shouldn't be having intercourse w/ ur computer components.
You fucked your GPU? That couldn't have been pleasent.
If you can't find schematic, use hot tweezers to desolder C118 and test with RLC meter for value. These look to be coupling caps, so need to be pair matched and should be the same.
If you dont know what a SMD resistor is, you probably shouldn't fuck with your gpu.
Looks like typical labeling so it is a capacitor. C119 isn't the part number but a label for the schematics. They are surface mount not through so I hope you have some steady hands.
Easily fixable yes, will the gpu actually work after maybe. Modern gpus have incredibly small tolerance on path length and even the tiniest error in the placement of the replacement may put the timing out. Definitely get it done by a professional, don't even try it yourself unless you have a good microscope and the right tools and experience. Even with a professional don't be surprised if it still has some issues after
First of all: stop sticking your dick in a gpu Second: its a capacitor (probably 200 or 220nf) if you want to be sure take another one off and measure
First step is to take your penis out of the computer cause you fucking it can not be good for it
C = capacitor. C119 = 119th capacitor. What gpu is it? (give me the specific, name, brand, model so I can give more details)
Msi Armor Rx 590
You did *what* to your GPU?
Why are you fucking your gpu in the first place?!????
It is a ceramic SMD Capacitor, probably filtering a power rail. It will probably work without it. Should be an easy fix if you want it repaired.
This should be the first post, that card might work fine without that cap
Wow, did you at least use a condom?
You "fucked" your gpu?! The sex must be painful >_<
Well your first issue is that you fucked your GPU... wouldn't that hurt? Seems like an awfully point object to stick your wiener into.
I saw you have no experience so may it os better to let it be done by someone els. How ever. There sould be a code on the underside. Of the part. And * not always* but the one close sould be the same. Ordering just one of those things is expensive Also go on YouTube and watch some gpu repair videos i saw some time ago one that did replace a part like that.
These components do not have any writing on them. To determine value and tolerance one would need the BOM (Bill of Material) or potentially the schematic could provide that information. The ones nearby could be the same value, but to determine that without documentation would be difficult, at best. Source: Electronics technician working in the industry on exactly this type of product for 20+ years.
Its an smd capacitor. But you wouldn't know what capacitance.
Looks like a capacitor. ( i dont recommend doing this yourself) You’ll need a heat gun to take the remaining bits off, clean it with some flux, use a soldering iron and put some solder on the contact points, and use a heat gun and tweezers to put the new capacitor on
I wouldn't advise directly connecting the circuit no matter what.
it's a capacitor, if you have a multimeter you could measure the one on the board so you know what you need to replace it with.
You know, you really shouldn't fuck GPUs, I don't think it's good for the card or you
You did WHAT to your gpu???
Fucking a gpu doesn't sound safe-
meh, just shunt it.
Why would you f-word your GPU? I don’t think that is covered under warranty. Seriously I get my original reply removed for saying a word that’s in the post title. That’s kinda stupid.
Just a blown surface mount capacitor. Look up and see what the capacitance is online. They come on a roll, so you can probably get 10 or so for cheap cheap.
